How do you the explain the changes in populations of organisms through time?
How do you the explain the changes in populations of organisms through time?
Evolution describes changes in inherited traits of populations through successive generations. Evolution is defined as the change in the inherited traits of a population of organisms through successive generations. When living organisms reproduce, they pass on to their progeny a collection of traits.
How does natural selection operate to cause change in a population?
Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population. Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
How does change in an environment cause the evolution of a species?
Environmental change and isolation of groups of organisms play an important role in evolution. Change in an organism’s environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species.
How can you use natural selection to explain and predict why these changes to the environment also affect organisms?
Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. Species become extinct because they can no longer survive and reproduce in their altered environment.
What law is survival of the fittest?
The principle of “survival of the fittest”, properly understood, is much more than a law of probability: it is a law of evolution. The principle should not be eliminated from the theory of natural selection because it plays an essential role in evolutionary theory, explanations, and research.

Herbert Spencer
Who is the fittest man in the world?
